Boost Your Minecraft FPS: The More FPS [FORGE] Modpack for 1.21
If your Minecraft sessions are plagued by stuttering, low frame rates, or that dreaded lag spike when you turn around too fast, you are not alone. Vanilla Minecraft can be surprisingly demanding, especially on older hardware or when you start adding content. The More FPS [FORGE] modpack steps in as a lightweight, focused solution that strips away performance bottlenecks without altering the core game. Updated for version 1.21, this pack gives you the tools to run Minecraft smoothly, even with shaders enabled.
What Makes This Modpack Different?
Many optimization packs throw dozens of mods together, sometimes causing conflicts or even reducing performance. More FPS [FORGE] takes a minimalist approach. It includes only essential, carefully tested mods that target specific areas of the game engine. You keep the vanilla experience intact while unlocking significantly higher frame rates. The pack is built around the Xenon rendering engine, a modern alternative to OptiFine’s pipeline that delivers superior performance on a wide range of GPUs.
Because the modpack adds nothing that changes gameplay, blocks, or mobs, you can safely layer your own favorite content mods on top. The optimizations actually help those mods run better, reducing the typical overhead that comes with large mod lists. This makes More FPS an ideal foundation for custom modded adventures.
Core Performance Mods at a Glance
Every mod in this pack has been chosen for a reason. Here are some of the key players that work together to boost your FPS:
- Xenon – The backbone of the pack, replacing the default rendering engine with a highly optimized one that supports modern shader features and reduces CPU overhead.
- FastSuite – Accelerates recipe and loot table calculations, preventing those micro-freezes when crafting or opening chests.
- Clumps – Groups experience orbs together, eliminating the lag caused by hundreds of individual entities floating around after a big fight.
- BadOptimizations – A collection of small, targeted fixes that patch inefficient vanilla code paths without any configuration needed.
- AttributeFix – Removes arbitrary limits on entity attributes, which can prevent weird performance dips in heavily modded environments.
- DespawnTweaker – Gives you control over item despawn timers, reducing clutter and keeping the world cleaner for the tick loop.
These mods work silently in the background. You won’t see new menus or confusing options. Just launch the game and enjoy a smoother experience. If you want to tweak settings later, each mod provides its own configuration file, but the defaults are already tuned for maximum compatibility.
Shader Support Without the Usual Pain
One of the biggest surprises with More FPS is how well it handles shaders. Thanks to the Oculus mod (a Forge port of the famous Iris shader loader), you can use almost any shader pack designed for OptiFine. The pack even includes the MakeUp – Ultra Fast shader by default, which is specifically designed to look great while keeping frame times low. You get dynamic shadows, waving foliage, and reflective water without watching your FPS plummet into the single digits.
During testing on a mid-range laptop, the combination of Xenon and MakeUp – Ultra Fast delivered a stable 60 FPS at 12 chunks render distance with shaders enabled. Without the pack, the same setup struggled to maintain 30 FPS. The difference is night and day.
Server-Side Improvements
Performance isn’t just about your local machine. More FPS includes mods that help when you are playing on a server or hosting one yourself. Spark, a powerful performance profiler, is bundled in. While it is primarily a diagnostic tool, it can help server admins identify lag sources and optimize tick rates. Combined with the client-side optimizations, you will notice fewer lag spikes and more consistent gameplay in multiplayer.
For those who like to experiment with their own server setups, the modpack’s lightweight nature means it won’t bog down a hosted instance. When you are ready to share your optimized world with friends, you can easily manage the mod list and updates. Speaking of which, this mod can be easily installed via the foxygame.net launcher — a convenient, flexible, and modern Minecraft launcher where you can download mods right from the menu. That way, you spend less time troubleshooting file folders and more time building.
Installation and RAM Allocation Tips
Getting the most out of More FPS requires a simple but critical step: allocate enough RAM. Many players forget that the default memory setting in the vanilla launcher is too low for modded play. If you see endless loading screens or single-digit FPS after joining a world, the fix is usually just a slider away.
- Open your launcher’s profile settings.
- Find the JVM arguments or memory slider.
- Set it to at least 2 GB (2048 MB). For larger mod lists on top of More FPS, 4 GB is a safe bet.
- Make sure you are using a 64-bit version of Java. Most modern launchers handle this automatically.
If you are using the CurseForge app, the process is even simpler: go to profile options, uncheck “Use system memory settings,” and drag the bar to the right. The modpack itself is extremely light, so it won’t demand excessive resources, but giving it enough breathing room prevents garbage collection stutters.
Compatibility and Expandability
More FPS [FORGE] is built for Minecraft 1.21 and uses the Forge mod loader. It is compatible with virtually any other Forge mod you want to add, from tech mods like Create to exploration packs like Biomes O’ Plenty. Because it does not touch world generation or game mechanics, you can drop it into an existing modpack as a performance layer. Many players use it as a base and then build their own themed experience, knowing the foundation is rock-solid.
The pack is part of a larger family of “More” modpacks by the same creator. If you enjoy this one, you might also look into More Animals, More Biomes, More Decorations, or More Dungeons, all designed to be stacked together without conflicts. Each pack keeps the same optimization core, so you never have to sacrifice FPS for content.
Conclusion
The More FPS [FORGE] modpack proves that you don’t need a high-end gaming rig to enjoy a beautiful, responsive Minecraft. By combining Xenon’s rendering engine with a handful of precision-targeted mods, it delivers a dramatic FPS increase while leaving the door wide open for shaders and additional content. Whether you are on an old laptop or a powerful desktop, this pack deserves a spot in your mods folder. Install it, tweak your RAM, and rediscover Minecraft without the performance headaches.
